alphaA-crystallin (HspB4), alphaB-crystallin (HspB5),
and the small heat shock protein (sHsp) HspB6, also
known as Hsp20. sHsps are molecular chaperones that
suppress protein aggregation and protect against cell
stress, and are generally active as large oligomers
consisting of multiple subunits. Alpha crystallin, an
abundant protein in the mammalian lens, is a large (700
kDa) heteropolymer composed of HspB4 and HspB5,
generally in a molar ratio of HspB4:HspB5 of 3:1. Only
trace amounts of HspB4 are found in tissues other than
the lens. HspB5 on the other hand is also expressed
constitutively in other tissues including brain, heart,
and type I and type IIa skeletal muscle fibers, and in
several cancers including gliomas, renal cell
carcinomas, basal-like and metaplastic breast
carcinomas, and head and neck cancer. HspB5's functions
include effects on the apoptotic pathway and on
metastasis. Phosphorylation of HspB5 reduces its
oligomerization and anti-apoptotic activities. HspB5 is
protective in demyelinating disease such as multiple
sclerosis (MS), being a negative regulator of
inflammation. In early active MS lesions it is the most
abundant gene transcript and an autoantigen, the immune
response against it would disrupt its function and
worsen inflammation and demyelination. Given as therapy
for ongoing demyelinating disease it may counteract this
effect. It is an autoantigen in the pathogenesis of
various other inflammatory disorders including
Lens-associated uveitis (LAU), and Behcet's disease.
Mutations in HspB5 have been associated with diseases
including dominant cataract and desmin-related myopathy.
Mutations in HspB4 have been associated with Autosomal
Dominant Congenital Cataract (ADCC). HspB6 (Hsp20) is
ubiquitous and is involved in diverse functions
including regulation of glucose transport and
contraction of smooth muscle, in platelet aggregation,
in cardioprotection, and in the prevention of apoptosis.
It interacts with the universal scaffolding and adaptor
protein 14-3-3, and also with the proapoptotic protein
Bax.

mammalian small (s)heat shock protein (Hsp)-27 (also
denoted HspB1 in human) and similar proteins. sHsps are
molecular chaperones that suppress protein aggregation
and protect against cell stress, and are generally
active as large oligomers consisting of multiple
subunits. Hsp27 shows enhanced synthesis in response to
stress. It is a molecular chaperone which interacts with
a large number of different proteins. It is found in
many types of human cells including breast, uterus,
cervix, platelets and cancer cells. Hsp27 has diverse
cellular functions including, chaperoning, regulation of
actin polymerization, keratinocyte differentiation,
regulation of inflammatory pathways in keratinocytes,
and protection from oxidative stress through modulating
glutathione levels. It is also a subunit of
AUF1-containing protein complexes. It has been linked to
several transduction pathways regulating cellular
functions including differentiation, cell growth,
development, and apoptosis. Its activity can be
regulated by phosphorylation. Its unphosphorylated state
is a high molecular weight aggregated form (100-800kDa)
composed of up to 24 subunits, which forms as a result
of multiple interactions within the ACD, and is required
for chaperone function and resistance to oxidative
stress. Upon phosphorylation these large aggregates
rapidly disassociate to smaller oligomers and chaperone
activity is modified. High constitutive levels of Hsp27
have been detected in various cancer cells, in
particular those of carcinoma origin. Over-expression of
Hsp27 has a protective effect against various
diseases-processes, including Huntington's disease.
Mutations in Hsp27 have been associated with a form of
distal hereditary motor neuropathy type II and
Charcot-Marie-Tooth disease type 2.

mammalian small heat shock protein (sHsp) HspB2/heat
shock 27kDa protein 2 and similar proteins. sHsps are
molecular chaperones that suppress protein aggregation
and protect against cell stress, and are generally
active as large oligomers consisting of multiple
subunits. HspB2 is preferentially and constitutively
expressed in skeletal muscle and heart. HspB2 shows
homooligomeric activity and forms aggregates in muscle
cytosol. Although its expression is not induced by heat
shock, it redistributes to the insoluble fraction in
response to heat shock. In the mouse heart, HspB2 plays
a role in maintaining energetic balance, by protecting
cardiac energetics during ischemia/reperfusion, and
allowing for increased work during acute inotropic
challenge. hHspB2 [previously also known as myotonic
dystrophy protein kinase (DMPK) binding protein (MKBP)]
is selectively up-regulated in skeletal muscles from
myotonic dystrophy patients. The ACD of hHspB2 binds the
DMPK kinase domain. In vitro, hHspB2 enhances the kinase
activity of DMPK and confers thermoresistance. The
hHspB2 gene lies less than 1kb from the 5 prime end of
the related alphaB (HspB4)-crystallin gene, with the
opposite transcription direction. These two genes may
share regulatory elements for their expression.

>gnl|CDD|107227 cd06470, ACD_IbpA-B_like, Alpha-crystallin domain (ACD) found in
Escherichia coli inclusion body-associated proteins IbpA
and IbpB, and similar proteins. IbpA and IbpB are 16
kDa small heat shock proteins (sHsps). sHsps are
molecular chaperones that suppress protein aggregation
and protect against cell stress, and are generally
active as large oligomers consisting of multiple
subunits. IbpA and IbpB are produced during high-level
production of various heterologous proteins,
specifically human prorenin, renin and bovine
insulin-like growth factor 2 (bIGF-2), and are strongly
associated with inclusion bodies containing these
heterologous proteins. IbpA and IbpB work as an
integrated system to stabilize thermally aggregated
proteins in a disaggregation competent state. The
chaperone activity of IbpB is also significantly
elevated as the temperature increases from normal to
heat shock. The high temperature results in the
disassociation of 2-3-MDa IbpB oligomers into smaller
approximately 600-kDa structures. This elevated activity
seen under heat shock conditions is retained for an
extended period of time after the temperature is
returned to normal. IbpA also forms multimers.

>gnl|CDD|107229 cd06472, ACD_ScHsp26_like, Alpha crystallin domain (ACD) found in
Saccharomyces cerevisiae (Sc) small heat shock protein
(Hsp)26 and similar proteins. sHsps are molecular
chaperones that suppress protein aggregation and protect
against cell stress, and are generally active as large
oligomers consisting of multiple subunits. ScHsp26 is
temperature-regulated, it switches from an inactive to a
chaperone-active form upon elevation in temperature. It
associates into large 24-mers storage forms which upon
heat shock disassociate into dimers. These dimers
initiate the interaction with non-native substrate
proteins and re-assemble into large globular assemblies
having one monomer of substrate bound per dimer. This
group also contains Arabidopsis thaliana (Ath) Hsp15.7,
a peroxisomal matrix protein which can complement the
morphological phenotype of S. cerevisiae mutants
deficient in Hsps26. AthHsp15.7 is minimally expressed
under normal conditions and is strongly induced by heat
and oxidative stress. Also belonging to this group is
wheat HSP16.9 which differs in quaternary structure from
the shell-type particles of ScHsp26, it assembles as a
dodecameric double disc, with each disc organized as a
trimer of dimers.

>gnl|CDD|233954 TIGR02622, CDP_4_6_dhtase, CDP-glucose 4,6-dehydratase. Members of
this protein family are CDP-glucose 4,6-dehydratase from
a variety of Gram-negative and Gram-positive bacteria.
Members typically are encoded next to a gene that
encodes a glucose-1-phosphate cytidylyltransferase,
which produces the substrate, CDP-D-glucose, used by
this enzyme to produce CDP-4-keto-6-deoxyglucose [Cell
envelope, Biosynthesis and degradation of surface
polysaccharides and lipopolysaccharides].

>gnl|CDD|130990 TIGR01935, NOT-MenG, RraA famliy. The E. coli member of this
family has been characterized as a regulator of RNase E
and its crystal structure has been analyzed. This model
was initially classified as a "hypothetical equivalog"
expressing the tentative hypothesis that all members
might have the same function as the E. coli enzyme.
Considering the second clade of enterobacterial
sequences within this family, that appears to be less
tenable. The function of these sequences outside of the
narrow RraA equivalog model (TIGR02998) remains obscure.
All of these were initially annotated as MenG, AKA
S-adenosylmethionine: 2-demethylmenaquinone
methyltransferase (EC 2.1.-.-). See the references
characterizing this as a case of transitive annotation
error in the case of the E. coli protein [Unknown
function, General].

>gnl|CDD|187562 cd05252, CDP_GD_SDR_e, CDP-D-glucose 4,6-dehydratase, extended (e)
SDRs. This subgroup contains CDP-D-glucose
4,6-dehydratase, an extended SDR, which catalyzes the
conversion of CDP-D-glucose to
CDP-4-keto-6-deoxy-D-glucose. This subgroup has the
characteristic active site tetrad and NAD-binding motif
of the extended SDRs. Extended SDRs are distinct from
classical SDRs. In addition to the Rossmann fold
(alpha/beta folding pattern with a central beta-sheet)
core region typical of all SDRs, extended SDRs have a
less conserved C-terminal extension of approximately 100
amino acids. Extended SDRs are a diverse collection of
proteins, and include isomerases, epimerases,
oxidoreductases, and lyases; they typically have a
TGXXGXXG cofactor binding motif. SDRs are a functionally
diverse family of oxidoreductases that have a single
domain with a structurally conserved Rossmann fold, an
NAD(P)(H)-binding region, and a structurally diverse
C-terminal region. Sequence identity between different
SDR enzymes is typically in the 15-30% range; they
catalyze a wide range of activities including the
metabolism of steroids, cofactors, carbohydrates,
lipids, aromatic compounds, and amino acids, and act in
redox sensing. Classical SDRs have an TGXXX[AG]XG
cofactor binding motif and a YXXXK active site motif,
with the Tyr residue of the active site motif serving as
a critical catalytic residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase numbering). In
addition to the Tyr and Lys, there is often an upstream
Ser and/or an Asn, contributing to the active site;
while substrate binding is in the C-terminal region,
which determines specificity. The standard reaction
mechanism is a 4-pro-S hydride transfer and proton relay
involving the conserved Tyr and Lys, a water molecule
stabilized by Asn, and nicotinamide. Atypical SDRs
generally lack the catalytic residues characteristic of
the SDRs, and their glycine-rich NAD(P)-binding motif is
often different from the forms normally seen in
classical or extended SDRs. Complex (multidomain) SDRs
such as ketoreductase domains of fatty acid synthase
have a GGXGXXG NAD(P)-binding motif and an altered
active site motif (YXXXN). Fungal type ketoacyl
reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.
